Its hard to say what your favourite killifish species are… but in my top 5 would have to be Nothobranchius furzeri; i’ve been keeping the Gona-Re-Zhou furzeri on and off for some time now, a long with other Mozambique collections since they became available in 1999.

And what an interesting animal. Furzeri actually holds the record of shortest living vertebrate - you’re pretty lucky if the fish live past 6 months old. Its also one of the longest kept strains in the killifish hobby, having been imported into America once in 1969 - and still going strong almost 40 years later.

It is regarded as one of the more difficult species to maintain long-term, but this need not be the case, if a few simple steps are taken.
